Acceptance Test Driven Development (ATDD and TDD)

Description

This course is a hands-on workshop intended to teach participants how to do Acceptance Test-Driven Development.  The class begins with an overview of Acceptance Test-Driven Development and Behavior-Driven Development.  Participants are taught to move from User Stories to Specification by Example, and then to use these examples in the creation of test cases.

 

Throughout the course, we use the Cucumber tool and Gherkin language.  Participants learn how to create executable acceptance tests that are the actual requirements.  From there, the steps in the feature are converted into Java step definitions.  Participants will work numerous examples where they create and execute acceptance tests for existing web sites and API’s

 

Special web sites built specifically to be tested are used in this course.  As part of the exercises, participants will learn to refactor both their test code and production code, create a Domain-Specific Language, and learn to use the Page Object Model pattern. 

 

Audience

The course is intended for testers, developers, quality engineers and managers who want a practical course in ATDD.  As programming exercises are included in the course work, a knowledge of Java is necessary.

Duration

3 Days
